through-a centrifugal pump, from an elec-- ftriemotor. I

holes 31 in thefplate' 18. As Shawn in. Fig.

4 these -..holes-are inclined, and the rotor is provided with .a' seriesof inclined vanes 32 against which r the water discharged through theholes 3Limpinges. The reac- -t1on-of the water against-thevvanes causesrotation of the rotor and of the spray-pipes carried thereby, while, the,water emerges through the pipes 24 and is conducted thence to thepoints where it is discharged, as reviously described.

t, has previously-been proposed to pro- -vi'de a. washing inaeaine v -tha rotary spraymg-device, but in such previous mains the rotation of thedevice has been secured by the reaction of theliquid in issuingthroughthe spray-orifices. Such an I arrangement has the. disadvantagethat it is-necessary. to direct the jets at a suitable angletoproduce-such rotation. By causing. rotation of the spra pipes by meansindependent-0f the reaction of the liquid in the spray-o nings, ispossible, in the present mac 'ne,.to arrange these openings at theangles most suitable for projecting the'spray with the maximum effectagainst the articles. Thus, as shown in Fig. 7, some of the openings inthe vertical pipes 25, may be directed in the direction of revolution ofthe'pipes, thus causing the spray to impings at an efifective angleagainst surfaces which mightnot be reached by-the oppositelydirectedsprays.- V j 'lnorderto wash the articles on the hasket 16, it isdesirable to project the spray "upwardly throughthe bottom of thebasket. For this purpose two of thespraypipes are arranged to carryinwardlyextending horizontal spray'pipes 33. These a, short vertical 3 Iwhich loosely embraoeshndturns on th 1 1'prlattei pipes are perforated,{as shown in Fig. 2, on their upper surfaces, and are closed at theiradjacent inner ends. When the basket-'17 is to- 'be .i-ntroducedor re-,imoved from the machine, together with its contents, it is necessary tomove the spray pi s 33 outof the way, and provision for 'th1s'is'"m'adeby connecting these pipes piv o tally .with the pipes 25. As shownparticularl in Fig. 6, ,the' spray-pipe 33 has per :extremity of] the-ffcorre sponding pipe 25.. A slot 35 in. thef'sl'e'eve '34 is engaged 33isin itsiiormal operative position, as

, When ,it is, necessary to f clean the: mac 'ne .liquid tbn dldHllngback-, .into .the bottom oil the casin and thus being repeatedlycirculated by t e-pur'np. For this purposean outlet opening 39. isprovided in the bottom of the casing, this opening delivering the liquidintoa chamber 40 formed integrally in a casting which constitii ts theforward raid notch, and I the' piple finay theii be swung eve 34 atit'siouter end, I Y

To prevent the spray-openings from becoming clogged by matter washedfrom the dishes or other articles, it is necessary tostrain the liquidbefore it'is delivered to the spraying-devices. For this purpose 9. cy-

hndrical strainer. 42 of wire-gauze or other .foraminous materialisarranged as shown in Fig. 1, the upper end of the strainer filling theoutlet-opening 39, while the lower end is seated in'an annular seat 43near the bottom of the chamber 40. This arrangement such that allof theliquid which passes from the casin to the pump must'first enter theupper en of the strainer and then emerge through the walls thereof,beingthus freed 1 .thence,--together wich the .:liqu id,,through theringAS;aeeries' of paral el wires 52 extends,
